Verdict for X-Plane 12
The Honeycomb Sierra TPM suits X-Plane 12 pilots flying Cessnas and other singles: three push-pull knobs (verniers) let you twist in cruise power and lean the mixture like the real panel. It's PC only, built for props, so airliner thrust levers aren't part of the deal.

Pros & Cons for X-Plane 12
Strengths
- Three push-pull verniers for throttle, prop and mixture — a vernier is a knob you twist for small, precise changes — so you can lean the mixture (the fuel-air knob) a hair at a time in the climb in a Cessna instead of nudging a keyboard key and watching the EGT jump.
- The trim wheel, landing gear lever, flap lever and parking brake mean the whole downwind checklist happens with your hands: gear down, flaps out, trim off the pressure, then set the brake once you're on the ramp.
- It fits the simmer who flies singles and light twins with a yoke, finishing a general aviation panel in X-Plane 12 rather than a jet cockpit.
Trade-offs
- Honeycomb Aeronautical doesn't say the levers use contactless (Hall-effect) sensors, which read position with a magnet and don't wear. Non-contact-free levers can drift or twitch with age, so expect to recalibrate or add a small dead zone in X-Plane 12 if the prop RPM starts wandering on its own.
- There are no airliner thrust levers or autopilot panel, and Honeycomb doesn't mention detents, so a jet departure still means reaching for the keyboard; the next step up in price buys more levers, detents and heading and altitude knobs.

Frequently Asked Questions
Is this a good Throttle Quadrant for X-Plane 12?
Yes, if you fly piston singles in X-Plane 12 — it scores 61.8/100 there, and that score reflects what it is: a general aviation module, not a jet quadrant. It shines on a Cessna run where you set takeoff power, pull the prop back to cruise RPM and lean the mixture by feel, with gear, flaps and trim right there. It shows its limits the moment you load an airliner, since push-pull knobs don't give you thrust levers, detents or reversers.
Is it worth the price for X-Plane 12?
For the money you're buying authenticity for one kind of flying: real push-pull vernier knobs plus gear, flap, trim and parking brake controls, which is a different thing from a generic three-lever quadrant. Spend more and you can get airliner-style levers, detents and an autopilot panel instead, so it comes down to whether your hangar is full of props or jets.
What does it need to work?
It's a PC-only module, which is fine here because X-Plane 12 runs on Windows PC and Mac and isn't on Xbox or PS5. It connects over USB to your computer, so you just need a free port — a powered hub helps if your yoke and pedals already fill the back of the case.
What else do I need with it?
Pair it with a yoke for general aviation flying, or a stick if you prefer, and rudder pedals so you can hold the centerline on a crosswind landing. On the desk, mount it on the side of your throttle hand, right beside the yoke, so your fingers find the knobs without looking down.
How should I configure this in X-Plane 12?
In X-Plane 12, assign each knob to its own axis — throttle, prop, mixture — then use the per-axis response curves to smooth out any twitch and set a small dead zone at the ends so idle and full power latch cleanly. Map the gear lever, flap lever and parking brake as buttons, and since there are no detents to feel for, set your cruise power by the gauge and remember where the knob sits.
